Product details

The STPS61H100CWY from STMicroelectronics is a dual common-cathode Schottky rectifier rated 100 V reverse voltage and 30 A average forward current per diode.

Forward voltage and conduction loss at 30 A

In a 30 A half-wave or center-tap leg, each diode dissipates roughly 24 W at full load; the TO-247-3 case with its large copper tab pulls that heat into the heatsink or chassis mount.

AEC-Q101 — what the automotive grade buys you

The -40 °C to 175 °C junction range covers cold-crank and under-hood hot-soak conditions without derating.

Frequently asked questions

Is STPS61H100CWY suitable for automotive applications?

Yes. It is released for production use in automotive ECUs, on-board chargers, and DC-DC converters without additional PPAP qualification.

What is STPS61H100CWY's listed speed?

The datasheet classifies it as a Fast Recovery diode with a recovery time of ≤ 500 ns at forward current > 200 mA. This is a Schottky device, so the recovery is majority-carrier — no stored charge to sweep out — and the 500 ns figure is a conservative upper bound for the datasheet classification.
